Sharon Standifird, a Houston mother and military veteran, said she created the app after she became frustrated and worried when her children did not answer her calls.

"We need to develop an app that just shuts their phone completely down and they can't even use it," she told ABC's Houston-owned station KTRK-TV. "I got on the Internet and I literally just started researching how to develop an app."

Several months later, she debuted the "Ignore No More" app for Android devices.

When she wants to lock her son's phone, Standifird opens the app and taps his name. She then enters an unlock code twice and then presses "Lock Bradley's Phone."

The activation of the app will take away a child's ability to play games, call friends and surf the Internet. The ability to call 911 will always remain intact on the phone, according its description in the Google Play store.

So how is Bradley, and other teenagers who are locked out, able to get back on their parents' good side?

With a single tap, they are provided with a list of contacts they can call to get the password to unlock the phone.

"I thought it was a good idea, but for other people, not me," Bradley Standifird told KTRK.
